I was somewhat hesitant to post this directly to the Forum because if IP restrictions, which is why I had WMW PM me. I found piece on-line in an unprintable format (Sibelius Scorch Plug-in), and copied it out by hand; I then transcribed it into MuseScore for my choir. It is the same version as that posted by Ben, although much cleaner, so please add the true editor's name if you are using it.
If it's of use to anyone, attached is an adaptation I made of this setting into English, using an English text that apparently I have misremembered the identity of. Only the addition of I think a single "O," and a "be" to the "liturgical" Gloria Patri were necessary. Slight melodic alteration that I think suits the English text better.
